No dilemma there. INSTRUCT.
50K to get 500 hours on type? Not gonna get you anywhere. It's all a numbers game in aviation: supply and demand. Tons of guys out there with plenty of time on type that you'll be competing against. Instruct, save your money, have fun, you'll learn so much more about yourself as a pilot. And trust me you will get to where you want to go via the instructing route. It will take a couple of years but when hiring starts you will be well ahead of fresh CPL holder with 250 hours TT. And when you are instructing: NETWORK, NETWORK, NETWORK.
Good luck!
